Exeter Chiefs have handed new contracts to front-rowers Chris Whitehead and Luke Cowan-Dickie.
Hooker Whitehead has signed a two-year deal, whilst prop Cowan-Dickie - who had one year left on his academy deal - has also been rewarded with a new contract.
Whitehead has played 50 times for the Chiefs since joining the club from Wasps.
England Under-20s starlet Cowan-Dickie has broken into the first team this year, playing four times.
"Chris is what I like about the way things have gone for us," said Exeter head coach Rob Baxter.
"He wasn't part of our promotion-winning team, but he came into that set-up very quickly and was one of the guys we looked to recruit based on his performances in the Championship against us whilst he was on loan at London Welsh.
"It's been a nice story of a gradual progression. It's not like he went straight into the side, he had to fight it out with other good hookers for quite a long time.
"It's been a good move for Chris to come to Exeter and we're glad it's worked out for us both. Now, though, I think the key for Chris, like a lot of the rest of our players, is to be part of a couple of big seasons for Exeter."
Baxter says he is particularly excited by 19-year-old Cowan-Dickie's prospects.
"He's one of the players you think wherever you pick him on a rugby field he can do damage because he's an exceptional ball carrier for his age," he added.
